--- title: Perforated Plate Sieves, Coffee Sieves, Grain Sieves description: Perforated plate test sieves, round square and other shaped openings, special grain & coffee sieves --- [![CSC Scientific Company, Inc.](https://www.cscscientific.com/hs-fs/file-1239671252-jpg/images/csc-logo-1.jpg "CSC Scientific Company, Inc.")](https://www.cscscientific.com/?hsLang=en-us) # Perforated Plate Sieves And Coffee/Grain/Nut Sieves # Perforated Plate There is a category of test sieves know as **Perforated Plate.** These Perforated Plate Sieves are constructed through a process of stamping holes in a sheet of thin metal. The size and shape of the holes are controlled by a die. These dies can be produced with a variety of shapes to deal with special grading needs for materials such as coffee and grain. They are normally used for openings greater than one millimeter in size. We offer a standard range of round hole **Perforated Plate Sieves** with openings from 1.16 millimeters to 5.0 millimeters. Other sizes and shapes are available on special order. ### Round Hole Perforated Plate Here's an example of **Perforated Plate Round Holes** for sieves: ![Perforated Plate Round Holes](https://www.cscscientific.com/hs-fs/images/Perforated%20Plate%20example%20of%20round%20holes.jpg?t=1481920130115&width=200&height=164&name=Perforated%20Plate%20example%20of%20round%20holes.jpg) ### Hexagon Shaped Hole Perforated Plate Here's an example of **Hexagon** shaped holes in **Perforated Plate Media**: ![Perforated Plate with Hexagon Holes](https://www.cscscientific.com/hs-fs/images/Perforated%20plate%20Hexagon%20holes.jpg?t=1481920130115&width=190&height=167&name=Perforated%20plate%20Hexagon%20holes.jpg) ### Special Order Hole Shapes There are a large number of options for hole shapes with **Perforated Plate Sieves**. Many are special order and may require onetime tooling costs. ![Perforated Plate Shapes Examples](https://www.cscscientific.com/hs-fs/images/Perforated%20Plate%20Shapes%20Examples.jpg?t=1481920130115&width=190&height=188&name=Perforated%20Plate%20Shapes%20Examples.jpg) ## See the Perforated Plate Sieves in our Online Store [![Go to the Sieve Store](https://no-cache.hubspot.com/cta/default/75757/6fe5a89b-4049-42d8-ac22-d8efc7a3e747.png)](https://cta-redirect.hubspot.com/cta/redirect/75757/6fe5a89b-4049-42d8-ac22-d8efc7a3e747) ## Additionally, we offer standards sizes of special coffee, grain and nut sieves #### **![Coffee Sieves](https://www.cscscientific.com/hs-fs/images/Coffee%20Sieves.jpg?t=1481920130115&width=77&height=97&name=Coffee%20Sieves.jpg)Coffee Sieves** We supply special sieves for grading coffee.
